NC中配置Servlet 调用NC服务

1.新建Servlet类（这个类中有实现调用接口的方法以及设置Token）路径没有要求，应该新建Servlet本来就不是规范。

package nc.impl.ca.cuma.account.ma;

import java.io.BufferedReader;

import java.io.IOException;

import java.io.PrintWriter;

import java.util.List;

import java.util.Map;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import nc.bs.ca.capub.service.NCLocatorFactory;

import nc.bs.framework.common.NCLocator;

import nc.bs.framework.comn.NetStreamContext;

import nc.bs.framework.core.service.IFwLogin;

import nc.jdbc.framework.processor.MapListProcessor;

import nc.pubitf.ca.cuma.account.ma.IMACoverPlanService;

import net.sf.json.JSONArray;

import net.sf.json.JSONObject;

public class CoverPlanServlet extends HttpServlet {

private static final long serialVersionUID = 1L;

private MapListProcessor myMapListprocessor;

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws IOException, ServletException {

response.setContentType("text/html;charset=utf-8");

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

JSONObject paraJson = JSONObject.fromObject(request

.getParameter("data"));

String userId = paraJson.getString("userId");

String groupId = paraJson.getString("groupId");

PrintWriter out = response.getWriter();

IFwLogin login =(IFwLogin)NCLocatorFactory

.getInstance().getCANCLocator().lookup("nc.bs.framework.core.service.IFwLogin");

NetStreamContext.setToken(login.login("yg","111aaa",null));

IMACoverPlanService PlanService = (IMACoverPlanService) NCLocatorFactory

.getInstance().getCANCLocator()

.lookup("nc.pubitf.ca.cuma.account.ma.IMACoverPlanService");

List<Map> coverPlanList=PlanService.getCoverPlanList(groupId,userId, null, null, "0", "10");

String returnJson = JSONArray.fromObject(coverPlanList).toString();

out.write(returnJson);

out.flush();

out.close();

}

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws IOException, ServletException {

this.doGet(request, response);

}

// public String readJSONString(HttpServletRequest request) {

// StringBuffer json = new StringBuffer();

// String line = null;

// try {

// BufferedReader reader = request.getReader();

// while ((line = reader.readLine()) != null) {

// json.append(line);

// }

// } catch (Exception e) {

// System.out.println(e.toString());

// }

// return json.toString();

// }

}

2.在account.portal.part中配置Servlet（注意使用一下LFW工具--->同步所有元素--->重启NC服务）

<?xml version="1.0" encoding="UTF-8" ?>

<web-app>

<context-param>

<param-name>ctxPath</param-name>

<param-value>/account</param-value>

</context-param>

<context-param>

<param-name>modules</param-name>

<param-value>account</param-value>

</context-param>

<servlet>

<servlet-name>CoverPlanServlet</servlet-name>

<servlet-class>nc.impl.ca.cuma.account.ma.CoverPlanServlet2</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>CoverPlanServlet</servlet-name>

<url-pattern>/CoverPlanServlet</url-pattern>

</servlet-mapping>

</web-app>

3.通过网页请求访问

http://IP：port/portal/CoverPlanServlet

4.简单的结果演示(CoverPlanServlet2只是我方便说明问题，不是上面的CoverPlanServlet)

5.第三方网页通过ajax请求如下（但是ajax会存在跨域问题，慎用，一般可以把第三方网页挂在NC工程中，这样就不存在跨域的问题了）

var json={"edit":[{"bh":"11111","mc":"11111","dbms":"ORACLE9i","dwmmc":"","addr":"","username":"","password":"","rm_sz":"ck","nyr_sz":"","id":"-1"},{"bh":"121","mc":"12","dbms":"ORACLE9i","dwmmc":"12","addr":"12","username":"12","password":"12","rm_sz":"ck","nyr_sz":"2011-09-06","id":"13"}],"del":["12"]};

var post={data:JSON.stringify(json)};//JSON.stringify(json)把json转化成字符串

//$.post(url,post);

$(document).ready(function(){

alert("ready in...");

//$("#send").click(function(){

alert("#send in...");

$.post("/portal/CoverPlanServlet",

post,

function(data,textStatus){

alert("数据：" + data + "\n状态：" + textStatus);

});

// });

});

6.第三方网页存放的位置
